ABSTRACT OF THE DISCLOSURE The invention relates to a round shaft bit with a bit head and a bit shaft, in which the bit shaft has a circumferential groove with a longitudinally slotted clamping sleeve positioned therein, and in which the bit shaft with the clamping sleeve placed under tension can be axially fixed in a bore of a bit holder whereby the bit shaft remains freely rotatable in the clamping sleeve. The insertion of the round shaft bit into the bore of a bit holder is, in accordance with the invention, significantly simplified and facilitated by the clamping sleeve being held in a clamping position by means of a holding element, in which the external diameter of the clamping sleeve is equal to or smaller than the diameter of the bore of the bit holder and that upon inserting the bit shaft with the clamping sleeve into the bore of the bit holder, the holding element moved onto an area of the bit shaft lying outside the clamping sleeve so that the clamping sleeve tensions against the interior of the bore holding the round shaft bit in axial position within the bore.
